Or trash disposal, however one wants to call it. :P
Not voluntary cleaning though, as a number of cheetahs sneaked into an enclosed storage lot of local colonial looters/scrappers and had quite the party there - end result being that on the next day they were forced to clean up their own trash and whatever stuff they broke beyond reuse.
In this particular case, the vacuum cleaner bag seems to be getting perilously close to 'full', too...
